MacArthur Network III, consisting of five nodes (locations) and over 100 investigators, was formed in 1983 to conduct collaborative clinical research on risk and protective factors associated with psychiatric disorders. The common measurement of attentional dysfunction associated with two specific disorders (schizophrenia and attention deficit-hyperactivity disorder) was a goal of a subgroup of 11 Network III investigators. In this paper, the experiences with five approaches for implementing common protocols on laboratory computers for collaborative clinical research are described. The reasons for selecting the approach provided by Schneider’s (1988) MEL system are presented and discussed. 相似文献

Unintentional injuries are the number one cause of death among children beyond one year of age. Many injuries among school-age children happen when they are away from home and in the company of peers. The aim in this study was to examine peer influences on children's judgments about engaging in behaviors that threaten their physical safety. Children were shown pictures depicting play situations which involved different paths of travel, each of which posed different degrees of injury risk. Children were asked to select the path they would take, and to assign a danger rating to reflect their beliefs about the likelihood of injury along this path. A peer-influence session followed, in which a same-sex friend attempted to persuade the child to take another path. Following exposure to the friend's arguments, children made their final decision about a path of travel in each play situation; the peer was not present during this decision and the experimenter present was unaware of the child's initial path choice. A number of other measures were taken in an effort to determine factors that influence children's risk-taking decisions. Results revealed that friends were successful in their persuasion efforts: for two of the three play situations, a significant number of children who initially selected low-risk paths switched to more risky paths. Appraisal of danger related to initial path decisions, but number of hazards identified and injury history did not significantly relate to initial decisions. The implications of these results for our understanding of injury-outcome processes are discussed. 相似文献

Individual differences in memory and suggestibility were assessed in an experiment involving 1989 people who attended the Exploratorium, a science museum located in San Francisco. Subjects watched a brief film clip of an assault and later answered questions about it. Approximately half received misinformation about some critical items. Four demographic variables (gender, educational level, age, and occupation) were examined to determine their impact on memory performance. The principle of discrepancy detection predicts that, compared to individuals with a good memory, people who have poor memory to begin with will be relatively suggestible (that is susceptible to misinformation). Some of our findings were consistent with this principle. For example, children (5–10 years) and elderly (over 65) were relatively inaccurate and also relatively suggestible. Other findings were not consistent with the principle, for example the finding that artists and architects were relatively accurate, but they were also highly suggestible. 相似文献

Twenty right-handed Ss listened to a dichotic tape in which one of six consonant-vowel syllables was paired with a burst of white noise on each trial. Eight blocks of 40 trials were presented, with the syllables within a block presented to, the same ear. On each trial, Ss decided if/ ba/ was presented. Mean RT to right-ear items was 440.0 msec, while mean left-ear RT was 453.6 msec. Responses indicating the presence of /ba/ were made significantly more quickly than responses indicating its absence, with no significant interaction of ear and type of decision. This study demonstrated a right-ear advantage in the perception of spoken syllables when noise is presented to the opposite ear. An interpretation of the RT differences between ears in terms of callosal transmission time is discussed, and implications of this study for the perceptual origins of the ear advantage effect are considered. 相似文献

Although the empirical studies of Terror Management Theory lend support to Ernest Becker's anthropology, they hardly provide a vision with the power to inspire late twentieth century humanity. Becker's own dark view of what it means to be human is, at least in part, to blame. On the basis of an exploration of the positive implications of the religious symbol of creatureliness, an alternative social theory, that of ecologico-social democracy, is proposed as a vision that requires and may even inspire heroism. 相似文献

Little is known of the retest reliability of emotional cognitive tasks or the impact of using different tasks employing similar emotional stimuli within a battery. We investigated this in healthy subjects. We found improved overall performance in an emotional attentional blink task (EABT) with repeat testing at one hour and one week compared to baseline, but the impact of an emotional stimulus on performance was unchanged. Similarly, performance on a facial expression recognition task (FERT) was better one week after a baseline test, though the relative effect of specific emotions was unaltered. There was no effect of repeat testing on an emotional word categorising, recall and recognition task. We found no difference in performance in the FERT and EABT irrespective of task order. We concluded that it is possible to use emotional cognitive tasks in longitudinal studies and combine tasks using emotional facial stimuli in a single battery. 相似文献

The traditional model of providing cancer predictive testing services is changing. Many genetic centres are now offering a choice to patients in how they receive their results instead of the typical face-to-face disclosure. In view of this shift in practice and the increasing demand on the ROI cancer predictive testing service, a 2 year retrospective study on patient preference in how to receive a Breast Cancer (BRCA) predictive result was carried out. Results showed that 71.7 % of respondents would have liked to have the option of obtaining their results by telephone or by letter. However, when asked about their actual experience of BRCA predictive results disclosure 40.6 % did still value the face-to-face contact, while 44.9 % would still have preferred to receive results by either post or telephone. No significant difference was found between males and females (p?>?0.05) and those who tested negative or positive for the BRCA mutation (p?>?0.05) in wanting a choice in how their results were disclosed. While the majority expressed a wish to have a choice in how to receive their results, it is important not to underestimate the value of a face-to-face encounter in these circumstances. 相似文献
